Hi,

Using super you can invoke constructor which is in parent
class. to invoke constructor which is in the same class we
have to use this. for example:

public class Point {
int m_x;
int m_y;

//============ Constructor
public Point(int x, int y) {
m_x = x;
m_y = y;
}

//============ Parameterless default constructor
public Point() {
this(0, 0); // Calls other constructor.
}
. . .
}
